Pseudotumor cerebri occurs when the pressure inside the skull ( intracranial pressure) increases without any obvious cause . Symptoms are similar to a brain tumor but no tumor was found . This condition is commonly referred to as idiopathic intracranial hypertension ( Iih ) .
Pseudotumor cerebri more common in children and adults , but the most commonly experienced are obese woman who was prolific childbearing .
Increased intracranial pressure associated with pseudotumor cerebri can also cause swelling of the optic nerve and loss of vision .
Cause
Experts suspect pseudotumor cerebri nothing to do with the excess amount of cerebrospinal fluid within the skull . In addition , the liquid produced by the brain will eventually be absorbed into the bloodstream . It could be an increase in intracranial pressure that causes pseudotumor cerebri is also a result of a disturbance in the absorption process .
According to some recent studies , the majority of patients with pseudotumor cerebri are known to experience a narrowing ( stenosis ) in the amount of two sinuses in the brain ( transverse sinuses ) . But researchers are also not sure whether it is a narrowing of one of the causes of pseudotumor cerebri or not .
Symptom
